The research sample consisted of 451 students who were selected by convenience sampling method and completed the childhood trauma questionnaire, personality organization questionnaire and borderline personality scale. Data were analyzed using the structural equation modeling method with the help of SPSS version 24 and LISREL 8.8 statistical software.
Findings: The findings showed that the direct path of childhood maltreatment to personality organization was positive and significant and to borderline personality symptoms was positive and non-significant. The direct path of personality organization to borderline personality symptoms was positive and significant. Additionally, the indirect relationship between childhood maltreatment and borderline personality symptoms was found to be mediated by personality organization.
Conclusions: The findings support the mediating role of personality organization in the relationship between childhood maltreatment and borderline personality symptoms. These findings showed that personality organization can play an indirect role in enhancing the effects of childhood maltreatment on borderline personality symptoms. Strengthening positive psychological characteristics and reducing risk factors, including traumatic childhood environments, and designing and using intervention programs can help reduce the symptoms of borderline personality.

Aim and Background: Research has increasingly shown a relation between childhood maltreatment and the dysregulated behaviors observed in individuals, yet the mediating factors in this relationship have received little attention. Thus, the primary aim of this study is to explore the role of cognitive processes as mediators in the relationship between childhood maltreatment and the dysregulated behaviors of individuals with bipolar disorder.
Methods and Materials: This study employed a descriptive and correlational research design. The statistical population consisted of all individuals with bipolar disorder who were hospitalized at Razi Psychiatric Hospital during the years 2023-2024. A total of two hundred individuals were selected for the research sample using convenience sampling. Data collection tools included the following: the Binge Eating Severity Scale (Gormally et al., 1982), the Deliberate Self-Harm Inventory (Gratz, 2001), the Alcohol Use Disorders Identification Test (Saunders et al., 1989), the Childhood Trauma Questionnaire (CTQ), the Cognitive Abilities Questionnaire (Nejati, 2013), the Difficulties in Emotion Regulation Scale- Short Form (Kaufman et al., 2016), the Acceptance and Action Questionnaire (Bond et al., 2011), and the Levels of Self-Criticism Scale (Thompson & Zuroff, 2004). Data analysis was conducted using SPSS and LISREL software, employing Pearson correlation and structural equation modeling techniques.
Findings: The study's results indicated that cognitive processes—including cognitive ability, self-criticism, experiential avoidance, and difficulties in emotion regulation—play a mediating role in the relationship between childhood maltreatment and dysregulated behaviors, such as alcohol consumption, binge eating, and non-suicidal self-injury, in individuals with bipolar disorder. The statistical fit of the model was strong, with the following indices: CFI= 0.96, NNFI= 0.95, IFI= 0.96, GFI= 0.92, and RMSEA= 0.072.
Conclusions: People with bipolar disorder who experienced childhood maltreatment often exhibit dysregulated behaviors due to cognitive processes. Therefore, clinical interventions focusing on cognitive processes are essential in preventing maladaptive behaviors in this population.
